摘要： A Moineau style stator includes a stator tube having a plurality of rigid helical lobes formed on an inner surface thereof. The helical lobes define a major internal tube diameter that is greater than a pass through diameter of the tube such that the major diameter undercuts the pass through diameter of the tube. A major liner diameter may also be less than the pass through diameter so as to provide a suitable interference fit between rotor and stator.

摘要： An accumulator comprises a housing connected to a hydraulic system, an elastomeric bladder separating a gas compartment from a fluid compartment, and an anti-extrusion device. A method for operating an accumulator comprises connecting the accumulator to a hydraulic system, injecting an inert gas into a gas compartment to a precharge pressure, moving an anti-extrusion device to prevent a bladder from extruding into the hydraulic system, running the accumulator and the hydraulic system downhole, moving the anti-extrusion device to allow fluid communication between the hydraulic system and a fluid compartment, generating pressure fluctuations within the hydraulic system, and expanding or contracting the bladder in response to the pressure fluctuations without moving the anti-extrusion device. A method of improving fluid hammer performance comprises connecting the fluid hammer to an accumulator that produces a greater delivered horsepower from the fluid hammer as compared to a baseline horsepower when operating without the accumulator.

摘要： A locking clutch to selectively transmit torque from a stator of a downhole tool to a rotor of the downhole tool includes at least one locking pawl radially between the rotor and the stator and configured to engage at least one recess formed in an outer periphery of the rotor, and a biasing mechanism configured to bias the at least one locking pawl into an engaged position. The at least one locking pawl includes a load path, two pivot axes, and a mass center. The at least one locking pawl transmits force from the stator to the rotor along the load path when in the engaged position, and centrifugal force urges the at least one locking pawl into a disengaged position when the rotor is rotated about one of the two pivot axes above a disengagement speed.

摘要： A locking clutch to selectively transmit torque from a stator of a downhole tool to a rotor of the downhole tool includes at least one locking pawl disposed upon the rotor. The at least one locking pawl comprises a load path, a pivot axis, and a mass center, and is biased into an engaged position by a biasing mechanism. The at least one locking pawl transmits force from the stator to the rotor along the load path when in the engaged position, and centrifugal force urges the at least one locking pawl into a disengaged position when the rotor is rotated above a disengagement speed.
